ProcSets are optional (and deprecated) - so don't rely on those... -----Original Message----- From: AJ Weber [mailto:awe...@comcast.net] Sent: Tuesday, February 14, 2012 11:42 AM To: itext-questions@lists.sourceforge.net Subject: Re: [iText-questions] Strip Annotations?
Yeah, I think in my case, I might compare the "length" of the Contents stream with the XObject stream (and see if they are drastically different -- I know with compression they would never be identical). In fact, I guess I could also check the /ProcSet for the /ImageB tag, and it's likely that there will be only one /XObject with a stream in it as the image of the whole page...
